With reference to FIG. 2A, further on the inside of the cabinet 20, a control board equipped with a central processing unit 51 (abbreviated as CPU below) that configures the control unit 50, an interface unit (or part) 52, a memory 53 and a storage 54 and the like are incorporated. The control board is configured so that communication is possible through the interface unit 52 and each of the components equipped on the cabinet 20, controls the operation of each part by executing the program recorded in the memory 53 or the storage 54 of the CPU 51, and provides a game to the player.

FIG. 2A shows a functional block diagram of the hardware of gaming machine 10, according to the present embodiment. The gaming machine 10 provides the control unit 50. The control unit 50 is configured as the interface unit 52 including a chip set providing communication functions of the CPU 51, a memory bus connected to a CPU, various expanding buses, serial interfaces, USB interfaces, Ethernet (registered trademark) interfaces and the like, and a computer unit where the CPU 51 provides the addressable memory 53 and the storage 54 through the interface unit 52. The memory 53 can be configured to include RAM that is a volatile storage medium, ROM that is a nonvolatile storage medium, and EEPROM that is a rewritable nonvolatile storage medium. The storage 54 provides the control unit 50 as an external storage device function, can use reading devices such as a memory card that is a removable storage medium, and a magneto optical disk and the like, and can use hard disks.

On the interface unit 52, in addition to the CPU 51, the memory 53, and the storage 54, a bill/ticket identification unit 55, a printer unit 56, the player tracking unit 57, a graphic controller 58, an input controller 59, and a sound controller 60 are connected. That is, the control unit 50 is connected to the operation unit 36 through the input controller 59, and connected to the upper display 22 and/or the lower display 24 through the graphic controller 58.

Further, when illumination that provides decorative lighting to the gaming machine 10 is provided, the illumination is controlled under the control of the control unit 50 on the interface unit 52, and an illumination controller 61 that provides a decorative lighting effect by way of one or more illumination unit 62 may be connected. One illumination unit 62 may be provided at a peripheral surface of the cabinet 20 so as to form a line surrounding the upper display 22, the lower display 24, and the control panel 26. Additionally or alternatively, another illumination unit 62 may be provided at a topper unit 68 on the outer periphery of a topper display 70. The illumination unit 62 may have, for example, (1) semi-transparent white acrylic resin/plastic parts exposed on the cabinet 20, and (2) one or more RGB LED modules behind the acrylic resin/plastic parts (not shown). The control unit 26 may control turning illumination on/off, color balance of the RGB LED modules, and total brightness of each RGB LED modules via illumination controller 62 to perform a visual effect (e.g., illumination).

Moreover, when a stage effect is provided within the gaming machine 10, the stage effect is controlled under the control of the control unit 50 on the interface unit 52, and a stage effect controller 63 that provides a stage effect by way of a stage effect unit 64 may be connected. The stage effect controller 63 may control other functional blocks (e.g., upper display 22, lower display 24, sound controller 60 with speakers 30 and/or illumination controller 61 with illumination unit 62) to perform a predetermined stage effect.

The control unit 50, which includes memory 53 and storage 54, controls each part by executing a program stored in the memory 53 and the storage 54, and provides a game to the player. Here, for example, the memory 53 and storage 54 may be configured to store a program and data of an operating system and subsystem that provide the basic functions of the control unit 50 to the EEPROM of the memory 53, and stores a program and data of an application that provides a game to the storage 54. According to such a configuration, it can be easy to change or update a game by replacing the storage 54. Further, the control unit 50 may be a multiprocessor configuration that has a plurality of CPUs.

Each block connected to the control unit 50 is described below. The bill/ticket identification unit 55 corresponds to the bill/ticket identification unit 32, receives bills or tickets in the insertion opening, and notifies the control unit 50 of identifying information corresponding to the assortment of bills or the payout processing of credits. The bill/ticket identification unit 55 notifies the information to the control unit 50, and the control unit 50 increases the usable credit amount inside of the game according to the notified content. The printer unit 56 corresponds to the printer unit 34, and under the control of the control unit 50 that receives an operation of the payout button of the group of setting buttons 38, information corresponding to the credit payout processing from the gaming machine 10 is printed and output on a printed ticket.

The player ranking (or tracking unit) unit 57 cooperatively operates with the control unit 50, and sends and receives information and the like of the player from the casino management system. The graphic controller 58 controls the upper display 22 and the lower display 24, under the control of the control unit 50, and displays a display image that includes various graphic data. The sound controller 60 drives the speakers 30 under the control of the control unit 50, and provides various sounds such as an announcement, sound effects, BGM and the like. Further, the interface unit 52 has various communication interfaces for communicating with the exterior of the gaming machine 10, including a former gaming machine 65 and a next gaming machine 66 in the series of gaming machines of the present embodiment.

FIG. 2B shows a functional block diagram of the software of gaming machine 10, according to the present embodiment. Each exemplary gaming machine 10 runs a game application 80, which includes a stage effect manager 81. The stage effect manager 81 of the game application 80 may be a software implementation of the stage effect controller 63. Middleware 82 connects game application 80 to an operating system 84. Middleware 82 includes a common timer 83, which shows the same time across each of the serially connected gaming machines 10.

Referring now to FIG. 3A, a reset signal path through a series of gaming machines is illustrated. To facilitate operation of the common timer 83, the first gaming machine in a series of gaming machines may be designated as the “master” gaming machine and each of the remaining gaming machines in the series may be designated as a “slave” gaming machine. Referring now to FIG. 3A, a series of gaming machines 100 includes master gaming machine 101. Master gaming machine 101 sends a reset signal that resets the common timer 83 in each of the slave gaming machines 102. The arrows illustrate the reset signal path through the series of gaming machines 100. By this common timer 83, each of the series of gaming machines 100 can perform associated stage effects and associated stage effects transition(s) based on common present time information. In a preferred embodiment of the present invention, a series of 256 individual gaming machines 10 may be connected, where gaming machine 0 is designated as the master gaming machine 101, and gaming machines 1-255 are designated as slave gaming machines 102.

In some embodiments of the present invention, the common timer 83 may consist of two types of timers: a delay timer (e.g., a 1-millisecond delay timer) and a status timer. The delay timer is required for implementation of the association of a stage effect amongst a series of gaming machines. The delay timer may comprise a 21-bit counter with millisecond increments (e.g., one millisecond increments). The status timer is not required for the implementation of the stage effect association feature. The status timer includes a 3-bit counter to increment every reset signal generated by the master gaming machine 101 for a predetermined period of time. The delay timer is cleared by after the status timer reaches a predetermined value. When the status timer reaches the predetermined value, a “1” is added to the timer, which in turn clears the value of the status timer. For example, when the status timer reaches ‘111’, +1 is added and the value returns to ‘000’. An exemplary status timer cycle is shown as follows, with exemplary values corresponding to predetermined time periods (in seconds): 000 [58.192s]→001 [134.657s]→010 [66.278s]→011 [134.653s]→100 [58.195s]→101 [134.655s]→110 [66.281s]→111 [134.656s], where the entire cycle is 13 minutes and 7.571 seconds. Use of this cycle prevents time errors from accumulating within the software process. FIG. 3B illustrates the relationship between the delay timer and the status timer.

When a slave gaming machine 102 is switched off, the predetermined period of time of the status timer may lead a maximum of 6 seconds and reconstruction of the connection between master and slave may occur. The delay timer may gain about 5 seconds for reconstructing the connection. Care should be taken to avoid a disruption in the desired associated stage effect being performed. An idle period, where no stage effect is performed, may be programmed to be initiated during the turning on and off of slave gaming machines 102 or when one stage effect is being switched for another.

Referring back to FIG. 2B, the operating system 84 further includes drivers 85, which provide software interfaces to illumination controller 61 that provides a decorative lighting effect by way of an illumination unit 62.

The gaming machine software further includes flash read-only memory (ROM) 86 for storing a machine ID 87. In an embodiment of the present invention, the machine ID 87 includes information that may be assigned to each gaming machine 10 in a series of gaming machines 100. Illumination controller 61 is configured to cause the illumination unit 62 to perform a predetermined stage effect based on timer information from common timer 83 and machine ID 87. Timer information may include time elapsed by the status timer and/or time elapsed by the delay timer. The machine ID 87 provides information about the location of a gaming machine 10 relative to the master gaming machine 101.

A machine ID 87 may be updated when the value of status timer is either “100” or “110”, as described above. Examples of updating the machine ID 87 are shown below, where “STV” is an abbreviation for “Status Timer Value”):

<Normal Operation>

Turn on all machines ID0->ID0->ID0->ID0->ID0->ID0->ID0->ID0-> . . .

STV: 000-011 ID0->ID0->ID0->ID0->ID0->ID0->ID0->ID0-> . . .

STV: 100 ID0->ID1->ID2->ID3->ID4->ID5->ID6->ID7-> . . .

<Turn Off a Gaming Machine>

Status Timer: Optional ID0->ID1->ID2->ID3->ID4->ID5->ID6->ID7-> . . .

Turn off 4^(th) machine ID0->ID1->ID2-> ****->ID0->ID5->ID6->ID7-> . . .

STV: Any except 100,110 ID0->ID1->ID2-> ****->ID0->ID5->ID6->ID7->.

STV: 100 or 110 ID0->ID1->ID2-> ****->ID0->ID1->ID2->ID3-> . . .

<Turn on a Gaming Machine>

Status Timer: Optional ID0->ID1->ID2-> ****->ID0->ID1->ID2->ID3->.

Turn on the 4^(th) machine ID0->ID1->ID2->ID0->ID0->ID1->ID2->ID3-> . . .

STV: Any except 100,110 ID0->ID1->ID2->ID0->ID0->ID1->ID2->ID3->

STV: 100 or 110 ID0->ID1->ID2->ID3->ID4->ID5->ID6->ID7->

Although it is possible to associate a stage effects among the series of gaming machines 100 by using common timer 83 alone, in some instances it may be desirable to delay stage effects between each gaming machine 10 among the series of gaming machines 100. For example, it may be desirable to perform an associated stage effect in a pattern such that the illumination flows from the left-most gaming machine 10 to the right-most gaming machine 10 in the series of gaming machines 100.

When sequential machine IDs 87 are assigned in a common series of gaming machines 100, each gaming machine 10 can identify its position within the series of gaming machines 100. Therefore, the series of gaming machines 100 performs more complex stage effects, such as synchronized effects based on a sequential ordering, or alternate or special stage effects based on specific positions of each gaming machine 10.

Referring now to FIGS. 4A-4E, the series of gaming machines 100 may perform a sequential stage effect by delaying illumination based on machine ID 87. Each of four gaming machines 10 in a series of gaming machines 100 may be given machine IDs 87: “1”, “2”, “3”, and “4” (FIG. 4A). The sequential stage effect may be ordered as 1-2-3-4, such that the gaming machine 10 that is assigned a machine ID of 87 “1” illuminates first in the series (FIG. 4B), the gaming machine 10 that is assigned a machine ID of 87 “2” illuminates second in the series (FIG. 4C), the gaming machine 10 that is assigned a machine ID of 87 “3” illuminates third in the series (FIG. 4D), and gaming machine 10 that is assigned a machine ID 87 of “4” is illuminated fourth in the series (FIG. 4E), where the illumination effect is illustrated by design 103. FIGS. 4A-4D illustrate only one example of a possible sequential stage effect. It will be understood that any ordering may be chosen, i.e., 4-3-2-1, 1-2-4-3, 1-3-4-2, and the like. The delayed illumination is a function of setting the ordering pattern and the predetermined delay interval in the game application 80.

Moreover, any gaming machine 10 can synchronously display illumination regardless of machine ID 87, so as to perform synchronous stage effects in the series of gaming machines 100. This is achieved by setting the machine ID 87 and “0” as the predetermined delay interval in the game application 80.

A series of gaming machines 100 may be placed on a gaming floor in any configuration that allows for operation of the associated stage effect. For example, FIG. 5A illustrates a machine layout 120, where two back-to-back rows of four gaming machines 10 (numbered with machine IDs 0-7) are connected at one end by the gaming machines 10 associated with machine IDs “3” and “4”, and a machine layout 121, having two back-to-back rows of four gaming machines 10 (numbered with machine IDs 0-3 and 0-3), where the two rows are not connected. In an alternate embodiment, as shown in FIG. 5B, machine layouts 122 and 123 each include gaming machines (numbered with machine IDs 0-3) arranged in a carousel formation.

Referring now to FIG. 6, a method for associating a stage effect among the series of operably interconnected gaming machines is illustrated. At a first step 140, each of the plurality of gaming machines is assigned a unique machine identification code. This step may be performed through setting operation of a casino attendant or retrieval of stored machine identification code from memory or stage of the gaming machine. At a second step 141, a common timer of each of the plurality of gaming machines provides timing information related to the display of a predetermined stage effect by a display unit of each of the plurality of gaming machines. At a third step 142, a control unit of each of the plurality of gaming machines performs the predetermined stage effect based on the timing information and the machine identification code.
